I want to store in my database a large text from an HTML file that could have Twig directives such as double curly braces, pipes, etc. From that string, I want to render a Twig template and send it back to the client.
public function renderAction (Request $request) {
$text = "<!doctype html>
<html lang='en'>
<head>
<meta charset='UTF-8'>
<title>Document</title>
</head>
<body>
{{SomeVariable}}
</body>
</html>";
$template = $this->render($text, $parameters);
return new JsonResponse(["status" => "ok", "template" => $template], 200);
}
When I try this I got an error, it seems like the first param from $this->render is always used as a path to a twig file but I will not be storing URI but the HTML file content in my database. Is there any way to render a twig template from a string?
I also tried using
$template = $this->get('twig')->createTemplate($text);
return new JsonResponse(["status" => "ok", "template" => $template], 200);
but the "template" prop is always empty when the client receives it
I am using Symfony 2.8.52 and PHP 5.6

I use hbs to render my pages with partials for navigation and footers.
router.get('/test', function (req, res) {
return res.render('test');
});
On one page I have template that uses mustache.js. This template doesn't work as it should as the {{}} seems to be picked up on the hbs render. Below is a basic example that illustrates the error. If I load this as a static page with express I get "Joe is a Web Developer", if I render it with hbs I get "is a".
Are there any work arounds that wont involve me changing how all my pages are rendered?
<!doctype html>
<html lang="en">
<head>
<title>Mustache.js Inline Method</title>
<script type="text/javascript" src="js/libs/mustache.js" ></script>
<script>
var view = {
name : "Joe",
occupation : "Web Developer"
};
function loadtemp(){
var output = Mustache.render("{{name}} is a {{occupation}}", view);
document.getElementById('person').innerHTML = output;
}
</script>
</head>
<body onload="loadtemp()" >
<p id="person"></p>
</body>
</html>
It was simple enough. I just had to escape the brackets with a \
So all it took was
\{{name}}
I am using the layout taglib to extend a page to its template but i don't know how to pass a variable to the main layout and apply a conditional class.
Considering this is my main-layout.marko
<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body class="#### (TITLE === 'REGISTER')?'ACTIVE':'INACTIVE' ####">
<layout-placeholder name="title"/>
<layout-placeholder name="body"/>
</body>
</html>
this is my registration.marko
<layout-use template="./layout.marko">
<layout-put into="title">
$data.title
</layout-put>
<layout-put into="body">
some content
</layout-put>
</layout-use>
and finally this is the code I use to render the page and pass the title data
router.get('/register', function(req, res, next) {
registration.render({
title: 'register'
}, res);
});
How can I create a conditional class on the main-layout.marko file that switches between active or inactive depending on the page title?
Thanks
You can pass data to a layout by adding additional attributes to your <layout-use> tag. See: marko-layout ยป Layout Data
For your example, the following will work:
In main-layout.marko:
<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body class="#### ${data.title === 'REGISTER' ? 'ACTIVE' : 'INACTIVE' } ####">
<layout-placeholder name="title">
${data.title}
</layout-placeholder>
<layout-placeholder name="body"/>
</body>
</html>
In registration.marko:
<layout-use template="./layout.marko" title="${data.title}">
<layout-put into="body">
some content
</layout-put>
</layout-use>
That should solve your problem, but let me know if you are still stuck.
there is another way of passing data t all of its template that is using $global in which you are passing your data .
and after using global you dont need to add attribute to any tag . you can access it by using like
out.global.username
I'm trying to run Twig (standalone, without Symfony 2) in a PHP project (Wamp) but it doesn't work : Twig shows the templates source code but does not execute the HTML. I don't find why. Here is my code :
index.php:
// DOCUMENT_ROOT (constant defined in a previous included file) : C:/Program Files/wamp/www/project
$sTwigPath = DOCUMENT_ROOT."/vendors/twig/lib/Twig/Autoloader.php";
if (file_exists($sTwigPath)) {
require($sTwigPath);
Twig_Autoloader::register();
$loader = new Twig_Loader_Filesystem(DOCUMENT_ROOT."/templates");
$tpl = new Twig_Environment($loader, array("cache"=>false));
try {
$oTemplate = $tpl->loadTemplate("home.html");
} catch (Twig_Error_Loader $e) {
error_log("Twig library not found", 0);
exit;
}
$aRender = array();
$aRender["myVar"] = "Wouah! myVar is displayed here!";
echo $oTemplate->render($aRender);
home.html :
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Home</title>
</head>
<body>
<h1>Home</h1>
{{myVar}}
</body>
</html>
I've no error (checked in PHP and apache logs).
I am using following code to create a html element in the page body with using YUI.
This code doesn't produce any error.
The issue is, the paragraph element is not created in the html page.
<html>
<head>
<title>YUI Test</title>
<meta charset="UTF-8">
<script src="http://yui.yahooapis.com/3.14.1/build/yui/yui-min.js"></script>
<script>
// Create a YUI sandbox on your page.
YUI().use('node', function(Y) {
// Create DOM nodes.
var contentNode = Y.Node.create('<p>');
contentNode.setHTML('This is a para created by YUI...');
});
</script>
</head>
<body>
<h1>Page body section...</h1>
</body>
</html>
The node is created, but it is also detached from the DOM. You have to attach it to the DOM by using either
Y.one('body').append(contentNode);
or
contentNode.appendTo(Y.one('body'));
or
Y.one('nav.main-navigation').insert(contentNode, 'before');
or any of the other methods for manipulating dom in YUI.
I trying to create main page (part of node.js and mongoDB application) that includes login form.
To add view part I included js files with function that returns HTML, but as I can see much better is using template engine.
Everything is OK until I including one compiled swig part inside another one.
The output of main page is OK, but login part outputs like text on the page.
How is possible to output the login HTML as HTML instead of plain text?
Does more information needed to understand the issue?
Thank you in advance.
var swig = require('swig');
var mainPage_tpl = swig.compileFile(__dirname+'/../views/mainpage_tpl.html');
var formLogin_tpl = swig.compileFile(__dirname+'/../views/login_tpl.html');
var loginOutput = formLogin_tpl();
var mainPageOutput = mainPage_tpl({
title: 'Sometitle',
pagetitle: 'Somepagetitle',
content: loginOutput
});
exports.get = function(req, res){
res.writeHead(200, {'Content-Type': 'text/html'});
res.write(mainPageOutput);
res.end();
}
mainpage_tpl.html:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>{{title}}</title>
<link rel="stylesheet" href="/assets/reset.css" />
<link rel="stylesheet" href="/assets/style.css" />
<script type="text/javascript" src="/assets/jquery-2.0.0.js"></script>
<script type="text/javascript" src="/assets/script.js"></script>
</head>
<body id="login_page">
<h1>{{pagetitle}}</h1>
<div id="content">{{content}}</div>
</body>
</html>
If you want to include literal HTML, you need to tell Swig to not escape it using the safe filter:
...
<div id="content">{{ content|safe }}</div>
...
